Answer:

Producing oxygen

Explanation:

Bacteria actually add to nutrients in soil because they decompose the organic matter such as dead bodies and such. I do not know if bacteria heal sick animals or if they prevent tooth decay rather I am sure they cause both of those.

Therefore, most plausible answer is producing oxygen because there are bacterias like cyanobacteria, or blue-green algae who go through photosynthesis and produce oxygen which is beneficial for all living beings.

nordsb [41]

Answer:

The correct answer would be B. The respiratory system supplies the oxygen that the cardiovascular system transports to the different cells for the production of energy.  

Respiratory system and cardiovascular system work together in order to provide oxygen to each cell of the body. They also help in removing the carbon dioxide (produced by cellular respiration) out of the body.

Respiratory system transport oxygen from outside the body to the alveolar site (in lungs). Oxygen is then carried in dissolved form with the help of hemoglobin (red blood cells) to all parts of the body.

Blood also carries deoxygenated blood (high carbon dioxide content) from all the cells to the alveolar site. The carbon dioxide is then excreted out of the body with the help of the respiratory system.
